Exodus 19:21-23

New Living Translation

²¹ Then the Lord told Moses, “Go back down and warn the people not to break through the boundaries to see the Lord, or they will die. ²² Even the priests who regularly come near to the Lord must purify themselves so that the Lord does not break out and destroy them.”

²³ “But Lord,” Moses protested, “the people cannot come up to Mount Sinai. You already warned us. You told me, ‘Mark off a boundary all around the mountain to set it apart as holy.’”
